Both sound fine. Very slight difference in meaning but inconsequential in this informal kind of speech.

Sorry, OT... One day the army unit stations a philosophy student as sentry. If he hears a sound, he is supposed to call out: "Who goes there?" But this guy, when he thinks he heard a sound, but isn't sure, calls out: "Who would go there?"

I don't see how this is OT. The question is asking about the usage of "who would go" versus "who goes." The OP gives also the context for which he is asked, which means it's not a too generic question. It could be the answer doesn't change basing on the context, but that doesn't make the question OT.

Can we use "There is this one driver" at the beginning in a hypothetical situation?
–

No, because you are asserting ("there is this one driver"), so there is nothing hypothetical about it.

But we can say: "there would be this one driver", right? I am just looking for alternatives instead of might.

No. The only sense I can make of that ("would" with the main verb) is past habitual (like "used to be"). To get a hypothetical you need to use either a verb like "might" or "could be", or a condition "if there were".

That example makes no more sense than the earlier ones. If you want to use "would" you need to be talking about either habit in the past, or about a hypothetical situation: but for the latter you need something (usually an explicit conditional, but in can probably be contextual) to establish the hypothetical context. I don't understand why you keep asking variations on the question "Can I use 'would' in this way you've told me I can't".
